2,6-Dibromo-4-methylnicotinonitrile CAS 38824-75-8

Description

Compared with other compounds in its class, the molecular weight of 275.93 g/mol gives 2,6-Dibromo-4-methylnicotinonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,6-Dibromo-4-methylnicotinonitrile (CAS 38824-75-8) is a high-purity analytical reference standard with the molecular formula C7H4Br2N2 and a molecular weight of 275.93 g/mol.

The molecular framework of 2,6-Dibromo-4-methylnicotinonitrile (C7H4Br2N2) is characterized by a nitrile group, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2,6-Dibromo-4-methylnicotinonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
